It mounts on a 35 mm DIN rail or screws directly to a panel backplate, with vertical orientation specified for proper heat dissipation. The supplied contactor is a 3RT2024-1AK60, and the link module is 3RA2921-1AA00, so replacement parts are known quantities. ## Duty ratings and trip class Coil voltage range is 88–121 V at 50 Hz and 96–132 V at 60 Hz, so it works on 110 V control transformers common in North American and European panels. ## Panel integration and clearances Dimensions are 120 mm deep, 90 mm wide, 265 mm tall — the S0 footprint fits standard 200 mm deep enclosures with room for gland plates. Required clearances: 50 mm above, 32 mm in front, 10 mm below, and 10 mm at the sides — plan the backplate layout so the starter isn't boxed in against cable ducts or other devices.","metaTitle":"Siemens 3RA2220-1GB24-0AK6 Reversing Starter, S0","metaDescription":"Siemens 3RA2220-1GB24-0AK6 SIRIUS reversing starter, S0 size, 2.2 kW at 400 V AC-3, Class 10 thermal overload.
